FOUNTAIN -PEN.

Specification of Letters Patent.

Patented Oct. 18, 1921.

Application filed April 29, 1920. Serial No. 377,575.

To all whom it may concei it:

Be it known that we, HENRY L. PEREZ and THOMAS VErroH, citizens of the United States, and residents of Yonkers, in the county of Westchester and State of New York, and Englewood, in the county of Jersey, respectively, have invented certain new and useful Improvements in Fountain-Pens, of which the following is a specification.

The present invention relates to fountain ens.

p Ordinary fountain pens hold but a relatively small supply of ink, and their usefulness is conditioned upon access to an ink supply at frequent intervals. It has been proposed heretofore to use tablets or powder, capable, by the addition of water, of forming a writing fluid or ink, said tablets or powder, as the case may be, being stored in a magazine, forming part of the fountain pen. In these constructions, the user, in order to place a tablet or a predetermined quantity of powder into the pen barrel, ordinarily must detach the magazine, or a part thereof, from the pen, which is a rather inconvenient and annoying operation.

The main object of the present invention is to provide a fountain pen, having an inkpaste containing magazine, in combination with a simple and eiiiciently operating mechanism for forcing, at will, suitable quantities of ink-paste into the pen barrel, containing water for dissolving the paste and thereby producing a writing fluid.

Another object of the invention is to so design the ink-paste magazine that it forms part of the barrel, thereby making it impossible to mislay the same, the paste charging means being, preferably, so arranged that it constitutes the means for closing the opening of the magazine, through which the filling operation takes. place.

A further object of the invention is to so construct the communication between the pen barrel and the paste magazine that the fluid in the barrel is effectively prevented from entering the saidmagazine.

A still further object of the invention is to produce a fountain pen of the type described, which is capable of manufacture upon a commercial scale, or in other words one which is not so diflicult to make as to be beyond the reasonable cost of such a contrivance.

' valve 14, which is held by With these and other objects in view, which will more fully appear as the nature of the invention is better understood, the same consists in the combination, arrangement and construction of parts hereinafter described, pointed out in the appended claims and illustrated in the accompanying drawings, it being understood that many changes may be made in the size and proportion, of the several parts and details of construction within the scope of the appended claims, without departing from the spirit or sacrificing any of the advantages of the invention.

A few of the many possible embodiments of the invention are lllustrated in the ac companying drawings, in which Figure l is a longitudinal sectional View of a fountain pen constructed in accordance with the present invention; Figure 2 is a similar view of a portion of a modified construction; Fig. 3 is a section taken on line 33 of Fig. 2, on a larger scale; and Fig. 4 is a longitudinal section through a portion of a further modification of the invention.

Referring now first to Fig. l of the drawings, the numeral 10 indicates the barrel of a fountain pen, carrying at its lower end the pen-holder section 11 in the usual manner of fountain pen constructions. A transverse partition 12 is formed in the barrel in proximity of its upper end, said partition being provided with a small opening 13, controlled by a check valve, for instance a ball means of a spring 15 upon its seat, said valve opening toward said pen-holder section, that is to say toward the fluid reservoir 16, disposed below said partition.

The barrel section above the partition is cylindrical and provided with interior screw threads 17, in mesh with those of a plug 18, the latter closing the last-mentioned barrel section, which constitutes a magazine for the ink material 19, thatmay be either a paste or viscous material. The outer end of the plug is provided with a milled knob 20, to facilitate the rotation thereof, while upon its inner end is mounted, in any suitable I filled, holds a suppl sufficient for several months, the plug, w en in operative position, shown in Fig. 1 of the drawln bearing against the ink material throng out the area of the barrel, and the check valve 14 closing a communication between themagazine and the fluid reservoir 16.

In use, the reservoir 16 is filled w th water in the usual manner, after whlch the plu 18 is given a turn, or part of a turn, to f irce the desired quantity of ml; materlal into the said reservoir, in which it guickly dissolves, whereb the pen is ready or use. In turning the p ug in the proper d1rect1on,

to force ink material into the fluid reser-- voir, the valve 14 is unseated against' the action of its spring 15, the latter seating the valve as soon as the turning movement of the plug ceases.

The modification shown in Figs. 2 and 3 of the drawings differs from the one above described, in that a disk-valve 221s employed instead of the ball valve 14. Th 1s valve constituting a check valve is made 1n the form of a cup-shaped body, the flat head 23 of which bears against the underface of the partition 12, while its 0 lindrical ortion 24 fits snugly the inner ace of the arrel 10. The cup-shaped bod is made of a suitable non-corroding, resi ient materlali for a purpose which will presently appear. In the fiat head 23 is formed a substantlally U-shaped slot 25, partly ing in the partition 12, while the cylindrlcal portion 24 of the said body is serrated to form resilient teeth 26, which bear against the inner face of the barrel, thereby holding the valve in position without the aid of special fastening means. The friction between these teeth and the valve is Sll'lllClGIlt to prevent a movement of the cup-shaped body, when the plug 18 is screwed down. to force ink material into the fluid reservoir 16. VVJren the said plug is turned for the purpose mentioned, the ink-material unseats that portion of the flat head 23 of the cupshaped body which is bounded by the slot 25, the resiliency of the said body causing the said portion to occupy its seat and thereby close the opening 13, as soon as the turning movement of the plug 18 ceases.

The several constructions herein described may be combined with self-filling fountain pens, one embodiment being shown in Fig. 4 of the drawings. In this case the partition 12' is detachable from the pen barrel 10, and to this partition is attached the fluid. containing rubber sack 30. An ordinary valve-disk 31 is employed for closing the opening 13 in the partition. This valve disk functions as a check valve. Otherwise the construction and operation of the elements are the same as of those described in connection with Figs. 1 to 4, inclusive, of the drawings.

encircling the open It. is obvious that, while herein specific valve constructions have been described for controlling the communication between the fluid reservoirs and magazines of the ens, others may gust as well be employed wit out departing rom the invention, which lies mainly in the provision of an ink material containing magazine, in combination with means whereby suitable uantities of the ink material are forcibly ed into the fluid reservoir.

A fountain pen including a barrel, a artition dividing the said barrel into a. iquid reservoir and an inkaste contain- 0 ing magazine, said partition eing provided with a check valve controlled 0 ening through which said reservoir and sai magazine are adapted to communicate, and means for forcibly feeding ink-paste from said magazine into said reservoir.

2. A fountain pen including a barrel, aartition dividing the said barrel into a liquid reservoir and an ink-paste containin magazine, said partition being provided wit a check valve-controlled o ening through which said reservoir and said magazine are adapted to communicate, and means for forcibl feeding varying quantities of inkpaste rom said magazlne into said reser- V011.

3. A fountain pen including a barrel, a partition dividing the said barrel into a liquid reservoir and an ink-paste containing magazine, said partition being provided with a check valve controlled opening through which said reservoir and said magazine are adapted to communicate, and means reach ing into said magazine only for forcibly feeding ink-paste from said magazine into said reservoir. 1
